We fitted a linear model (estimated using OLS) to predict trust_pct with s80s20 (formula: trust_pct ~ s80s20). The model explains a statistically significant and moderate proportion of variance (R2 = 0.19, F(1, 77) = 17.51, p < .001, adj. R2 = 0.17). The model’s intercept, corresponding to s80s20 = 0, is at 45.38 (95% CI (35.01, 55.76), t(77) = 8.71, p < .001). Within this model:
Standardized parameters were obtained by fitting the model on a standardized version of the dataset. 95% Confidence Intervals (CIs) and p-values were computed using a Wald t-distribution approximation. The model explains a statistically significant and moderate proportion of variance (R2 = 0.19, F(1, 77) = 17.51, p < .001, adj. R2 = 0.17)
